The Watching Lords

HAZARD 8
Stealth +18 (trained)
Description The demigod statues in the alcoves seem to shift, their heads turning to watch as intruders pass by.

Disable DC 31 Thievery (to scrape away hidden runes that grant the statues the ability to watch), DC 28 Religion (to pray for protection from the attention of Abyssal lords), or Dispel Magic (4th rank; counteract DC 26) to counteract the trap


Conjure the Guardians
Trigger A non-chaotic-evil creature approaches within 20 feet of the doors to area G4

Effect The statues appear to hiss and growl, and a moment later, four Brimorak demons appear in the hallway—two near the entrance to area G1, and two near the entrance to area G4. The four demons attack at once, rolling initiative as normal. They fight to the death, but vanish after 1 minute has passed.
Reset Once the Watching Lords are triggered, the trap needs an hour to recharge its energies, after which point it can be triggered again.
